The car had been setting for 18 months , Had half a tank of gas . used it up and refilled tank , replace fuel filter and regulator , the pump comes on with key and turns off as normal when engine is started fuel pump gets increasingly louder until engine shut off . removed vent to tank tube from bottom of regulator . regulator was venting gas normal did not make differance , when engine shuts off , it will restart and run normal if you turn key to off an restart . if you dont turn it all the way off ,but just restart it will run erattic until it dies.

You will probably have to replace the pump. Cars stored that long without a fuel stabilizer will deteriorate to the point that varnish will form on all parts in the fuel system.

Check fuel pressure with a mechanical gauge.
